I just done a backup of my iPod touch 5G on iMac with iTune, to my surprise, after the backup, I check the backup copy size, less than 1G while my iPod touch usage is over 10G. So wonder what contents on my iPod touch were backupped? I thought all APPS, iBook contents, Photos, Podcast contents would be included in the backup, seems they are not, otherwise, my backup folder can not be smaller than 1G.
Thanks for your help and sharing
